Solubility Answer Key

1. 
Adding more solute to a saturated solution increases the amount of un-dissolved solute.
2. 
Those gases whose molecules are polar are much more soluble in which solvent than are nonpolar gases?
  1. Turpentine
  2. Toluene
  3. Hexane
  4. Water
3. 
Which of the following solvents would be classified as a dipolar solvent?
  1. [math]H_2O[/math]
  2. [math]CH_3OH[/math]
  3. [math]CH_3COOH[/math]
  4. [math]CH_3COOCH_2CH_3[/math]
4. 
When an ionic compound dissolves, it exists in a solution as ions.
5. 
When a covalent compound dissolves, it exists in solutions as a molecule.
6. 
In which of the following polar solvents are ionic and polar compounds most likely to be soluble?
  1. Water
  2. Benzene
  3. Diethyl ether
  4. Carbon tetrachloride
7. 
Which statement correctly describes a saturated solution?
  1. The solvent can dissolve more solute if it is added.
  2. The solvent cannot contain undissolved solute.
  3. The dissolved form of the solute is at equilibrium with the undissolved solute.
  4. The dissolved solute is not at equilibrium with the undissolved solute.
8. 
Polar solvents, like water, have molecules whose electric charges are unequally distributed, leaving one end of each molecule more positive than the other.
9. 
The equilibrium of sodium chloride with its ions in a saturated solution would be shown by which equation?
  1. [math]NaCl(s) harr Na^+(aq)+ Cl^-[/math](aq)
  2. [math]NaCl(s) rarr Na^+(aq)+ Cl^-[/math](aq)
  3. [math]NaCl(s) rarr Na(s) + Cl(aq) [/math]
  4. [math]NaCl(s) larr Na(s) + Cl(aq)[/math]
10. 
Why would the amount of dissolved oxygen in California’s 12,802 foot (3902 meters) high Tulainyo Lake, nestled in the Sierra Mountains, at 40ºC be less than that of dissolved oxygen in a lake near sea level at 40ºC?
  • Gas solubility is proportional to the gas partial pressure. If the temperature stays constant but the altitude is increased the amount of dissolved oxygen in the lake decreases because atmospheric pressure decreases with increasing altitude.
